Accessible to the Lean novice and shop floor employee, The Basics of Line Balancing and JIT Kitting explores line balancing and the pre-assembly of components into a finished product in a just-in-time fashion (JIT Kitting). It explains how to use time studies, develop yamazumi charts, discover and eliminate waste, balance your line, and create new standard work content for the shop floor. The book facilitates a clear understanding of the seven deadly wastes (muda) as well as what you can do to eliminate them from your facility. Describing the purpose and use of standard work, it explains how to properly staff work cells and how to develop flex plans for fluctuations in demand using this data. The first few chapters explain how to determine takt time and how to use that information along with time studies to identify when you are not meeting customer demand. The chapters on JIT Kitting explain how there are other advantages to kitting besides eliminating waste and increasing productivity. The book explains how you can use JIT Kitting to improve quality by having the parts available and limiting the options of numerous parts to the operator. It also provides the understanding needed to ensure the right parts are installed, thereby correcting issues with the build of materials.

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology.

Fortunately, there's help. The "sendmail Cookbook" provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem.

Each recipe in the "sendmail Cookbook" outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances.

The "sendmail Cookbook" begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:

Delivering and forwarding mail

Relaying

Masquerading

Routing mail

Controlling spam

Strong authentication

Securing the mail transport

Managing the queue

Securing sendmail

"sendmail Cookbook" is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the "sendmail Cookbook" and say good-bye to sendmail dread.

Any programmer working with text files today needs a way to deal with Microsoft® Word documents and their underlying Rich Text Format. RTF is notoriously difficult to work with, and our handy quick reference is the only book available on what many developers call "this maddeningly unstructured format." Small and easy to use on the job, RTF Pocket Guide focuses on the "workhorse" codes that programmers can't do without, including text style codes, paragraph formatting codes, and page formatting codes-- all with many examples of real use.

The current edition of Samba Pocket Reference covers Samba 2.x and the most important features of 3.0, which was under development as this book went to print. New options pertain to Samba's acting as a primary domain controller and as a domain member server, its support for the use of Windows NT/2000/XP authentication and filesystem security on the host Unix system, and access to shared files and printers from Unix clients.

The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server. This title is an indispensable companion to DNS & BIND, 4th Edition, the definitive guide to the critical task of name server administration. The cookbook contains dozens of code recipes showing solutions to everyday problems, ranging from simple questions, like, "How do I get BIND?" to more advanced topics like providing name service for IPv6 addresses.

System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. For system administrators who want a hands-on introduction to system performance, this is the book to recommend.

There is a rapid growth of automation in server rooms and data centers. The days of having many administrators running around busily configuring and maintaining servers are gone and have been replaced with droves of Salt-Minions; agents beavering away on the target nodes ensuring the configuration is as specified. This book covers Salt Open (also known as SaltStack Open) from the ground up and shows you how to work with two Linux distributions. You'll see how Salt Open is duplicated with ArubaOS and IOS networking devices, which can be configured without the underlying OS. As you step through the configuration options, you'll learn how to run remote execution modules from the CLI before looking at stateful configuration using SLS files. Moving on, you'll learn how to configure the systems where you also need to monitor your devices and that is when reactors and beacons come into play. Creating beacons to alert the server when thresholds are exceeded, you will be able to create reactors to mitigate the issues identified by the beacons. By the end of this book, you will be able to deploy Salt to your servers and network infrastructure. You will be able to install the Salt-Master and Salt-Minion, executing commands from both the Master and the Minion. The networking devices you need to manage will be controlled through the Salt_Proxy Minions that you have configured. Finally, you will be able to load-balance connections to the master with Salt-Syndic. What You'll Learn Install Salt Services on Ubuntu and CentOS based systems Work with remote execution modules Format YAML files correctly Provide defined configuration using state files Use Salt-Proxy to configure network devices Automate the configuration of Linux servers and networking devices Add value for both the server and network automation team Who This Book Is For System administrators experienced in Linux administration, who desire to expand their horizons into the world of automation, moving from scripts to states.
